State Senator Kelvin Atkinson said Sunday he informed Kirkpatrick of Brooks' threat against her. Atkinson said Brooks had been telling people Kirkpatrick's "first day as speaker would be her last."

North Las Vegas police said Brooks, 40, was booked about 6 p.m. at the Las Vegas City Jail on a felony charge of intimidating a public officer by threat of physical violence. Jail records show Brooks was in custody Sunday evening.

Brooks is a Democrat serving Nevada Assembly District 17 in northern Clark County.
